9、t the observed effects of wind simulatedin a wind-tunnel apparatus are related to the effects observedfrom natural wind. The resistance of tiles to simulated wind inthis test relates to the resistance of the tiles to the effects ofnatural wind when they are applied to a roof. One factor in theresist

10、ance of the tiles to the effects of both natural andsimulated wind is the method of attachment specified in themanufacturers instructions. This test method determines theuplift forces acting as a result of the simulated wind when tileare attached to a section of roof deck in accordance with themanuf

11、acturers instructions. Natural wind conditions differwith respect to intensity, duration, and turbulence; theseconditions are beyond the means of this test method tosimulate.5. Apparatus5.1 The test assembly of tiles attached to a section of roofdeck is identical to that used in Test Method C1568 (M

12、echani-cal Uplift Method) except that tile are not fitted with aload-transfer device.5.2 The test assembly of tiles attached to the roof decksection is positioned on the floor of the wind tunnel apparatusas shown in Fig. 1.1This test method is under the jurisdiction of ASTM Committee C15 onManufactu

15、 International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Stand

16、ards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.16. Conditioning6.1 See the conditioning specified in Test Method C1568(Mechanical Uplift Method) for each specific installationsystem being investigated.7. Procedure7.1 Install the ti

17、le in the same manner as on a roof, inaccordance with the manufacturers instructions, on a smallsection of roof deck constructed to fit within the wind tunnelapparatus. The rafters shall be capable of being securelyanchored to the floor of the wind tunnel apparatus, and thesheathing firmly nailed to

18、 the rafters. Roofing underlayment isinstalled on top of the sheathing and, if required, battens arenailed to the sheathing. The tile, underlayment system, androof deck section constitute the test assembly.7.2 The test assembly for the tile installation system beinginvestigated shall be installed in

19、 the floor of the wind tunnelapparatus to cover area B in Fig. 1. Area A shall be used toprovide the boundary conditions for the flow over Area B. Thetiles in Area A shall be firmly fixed to the floor of the windtunnel apparatus. The tiles along the side of the test assemblyshall be sealed with adhe

20、sive tape to prevent air flow betweenthe underside of the tiles and the slow moving layer of air onthe floor of the wind tunnel. Roof sheathing shall have at leastone transverse joint in the test assembly to simulate air leakagefrom within the building.7.3 When testing Hip and Ridge tiles, they shal

21、l be as-sembled on the test deck in the same manner that they wouldbe applied to a roof in accordance with the manufacturersinstructions.7.4 Specimens shall be tested at a surface temperature of750F (210C) plus or minus 50F (30C) measured with asurface mounted thermocouple and recorded on a chart to

22、confirm that the surface temperature meets the required testtemperature.7.5 The pressure distribution on tile top of the tile shall hemeasured by placing 20 pressure taps in a single tile in Area B.The pressure distribution shall be taken above the tile by asuitable pressure measuring device that pe

23、rmits the rapidsampling of the pressure on all pressure taps. The pressure onthe bottom surface of the tile shall be measured by pressuretaps open to the underside of the tile.7.6 A plenum chamber shall be installed below the tiles inArea B. The chamber shall be connected via a swing valve toa fan.

24、The test shall be conducted with a pressure in the plenumchamber set to simulate an internal building pressure of +0.2.7.7 The wind speed over the test assembly shall be mea-sured using a pitot-static tube as shown in Fig. 2. ThePitot-static tube shall be positioned 4 in. (102 mm) above thetiles in

25、the free stream. Pressure tube connections shall bemade to the pitot-static tube so that the total pressure head(pitot + static) and the static pressure alone can be measured.The velocity (dynamic) pressure shall be determined bysubtracting the static pressure from the total head.7.8 The wind tunnel

26、 shall be taken up to a wind speed of 70mph (31 m/s) measured at the pitot-static tube position. Thisspeed will he held steady for 60 s and then readings shall betaken. The wind speed will then increase to 80 mph (36 m/s)and be held at this speed for 60 s before the readings are taken.This procedure

27、 will be repeated in 10 mph (4 m/s) incrementsuntil a wind speed of 130 mph (58 m/s) is reached, themaximum wind speed of the wind tunnel is reached, or the testassembly has failed. If the test assembly fails, the wind speedwhen the roof covering is removed shall be recorded. If theroof covering is

28、not removed, then the maximum wind speedobtained in the test shall be recorded.7.9 The net pressures on the tile shall be used to determinethe aerodynamic uplift force (overturning moment) on the tileas a function of the velocity pressures of the various windspeeds in the free stream. The wind veloc

29、ity of the free streamshall be correlated to the fastest mile wind velocity used in thecode.8. Failure8.1 The failure criteria are described for each specificinstallation system and tile in Test Method C1568 (MechanicalUplift Method).9. Report9.1 The report shall include the following:9.1.1 A statem

30、ent that the test or tests were conducted inaccordance with these test procedures. Deviations from thesetest procedures shall be described in the report and the effect ofany deviations on the test results shall be explained in thereport.9.1.2 Descriptions of the framing system, concrete or clayroof

31、tiles, with sketches. The description of the concrete or clayroof tiles shall include as a minimum the following: tile profile;location of nail holes; location of clips; headlap; side laps;thickness; weight.9.1.3 A detailed description, with sketches, of the test setup,auxiliary apparatus, and equip

Precision and Bias10.1 PrecisionIt is no

36、t possible to specify the precision ofthe procedure in Test Method C1570 (Wind Tunnel Method)because the wind tunnel is a unique structure used only todevelop data and criteria for use in Test Method C1568(Mechanical Uplift Method), and to facilitate correlation of tileuplift resistance to the speed

37、 of the simulated wind.10.2 BiasNo information can be presented on the bias ofthe procedure in Test Method C1570 (Wind Tunnel Method)for measuring wind resistance of roof tiles because no materialhaving an accepted reference value is available.11.
